DSDA (“SIM feature”) with RM551E-GL?

Can you tell me if RM551E-GL supports (“SIM feature”) DSDA?

Is it correct, that if I use 2 SIM cards in the both slots, I shall see 2x Modems, when DSDA is available/enabled,

so something like /dev/cdc-wdm0 and /dev/cdc-wdm1, or similar wwan0 and wwan1?

Is there any AT command or other setting needed to enable this?

Is RM551EGL00AAR01A04M8G enough or is a newer software needed?

Many thanks for the clarification!

Dear @capiman
RM551E doesn’t Support DSDA.
